TECHNICAL FIELD

The present invention relates to a novel amine compound, which is useful as a base for hair and skin cosmetic compositions, a detergent, an emulsifying agent, a conditioning agent, or the like, an intermediate useful for the preparation thereof, and detergent compositions containing such an amine compound.

BACKGROUND ART

Surfactants such as alkylsulfates, polyoxyethylene alkylsulfates and alkylbenzenesulfonates have heretofore been used as detergents. However, many of these surfactants involve a problem that they irritate the skin to a somewhat strong extent upon their use. For this reason, surfactants low in skin irritation, such as alkylphosphates and salts of acylated amino acids, have come to be used as bases or emulsifying agents for hair and skin cosmetic compositions, or detergents for the skin and the like. With the diversification of consumer demand and inclination to high-quality goods, there have recently been demand for development of compounds which have good foamability and such effects that a pleasant feeling can be given to the user's skin and the like, in addition to low irritativeness to the skin and the like. However, no compound fully satisfying these requirements has been yet developed.

Accordingly, it is an object of the present invention to provide a compound which can solve the above problems, has low irritativeness to the skin and the like and excellent foamability, can give a pleasant feeling to the user's skin and the like, and is useful as a base for hair and skin cosmetic compositions, a detergent, an emulsifying agent, a conditioning agent, and the like.

In view of the foregoing circumstances, the present inventors have carried out an extensive investigation. As a result, it has been found that novel amine compounds represented by the general formula (1), which will be described subsequently, can serve as anionic surfactants, have low irritativeness to the skin and the like, give a pleasant feeling to the user's skin and the like, and have excellent foamability, thus leading to completion of the present invention.

Incidentally, as compounds having a structure close to that of the compounds according to the present invention, there have been known compounds having a 2-hydroxypropanediamine structure (U.S. Pat. No. 3,654,158, DE Patent No. 3,607,884, U.S. Pat. No. 4,982,000 and Japanese Patent Application Laid-Open Nos. 233264/1989 and 223515/1990, etc.). Since these compounds have a diamine structure and besides have no anionic functional groups such as a carboxyl group, a sulfonic group and a sulfuric acid residue, however, they are greatly different from the compounds of the present invention, which are anionic surfactants having a triamine structure, in both structure and function.

Referential Example 1

A reactor was charged with 50 g (0.67 mole) of glycine, 70 g of water and 27 g (0.67 mole) of sodium hydroxide, and the contents were cooled down to 5° C. Thereafter, 124 g (1.34 moles) of epichlorohydrin were added dropwise over 1.5 hours, and the resultant mixture was heated up to room temperature. After the mixture was stirred for 6 hours, insoluble matter deposited was separated by filtration and dried to obtain 106 g (isolation yield: 56%) of sodium N,N-bis(3-chloro-2-hydroxypropyl)-glycine as white powder.

<Testing method>

Beef tallow added with 0.1 wt. % of Sudan III (a red coloring matter) as an indicator was applied in an amount of 2.5 g to a porcelain dish (diameter: 25 cm). The thus-smeared dish was rubbed and washed at 40° C. by means of a sponge with 3 g of the detergent sample and 27 g of water (hardness: 3.5° DH) soaked therein. The above-described test was conducted on ten panelists to evaluate the detergent sample in the detergency, feeling upon use, etc.

<Results>

As a result, the dishwashing detergent in which the compound according to the present invention was incorporated was good in foaming power, high in detergency and low in irritativeness to the hands and gave users a pleasant feeling upon use.
